My main research project is about the disease burden of RSV infections in young children in primary care - the RSV ComNet project -. In this project we have developed and evaluated a standardised disease burden protocol to measure the clinical and socio-economic disease burden of RSV infections in young children in primary care. We have evaluated the protocol in the winter of 2019/20 in Italy and the Netherlands. After evaluation we have updated this standardised disease burden protocol and we are implementing the revised protocol in more European countries in the winter of 2020/21. In addition, I am involved in the Global Epidemiology of RSV in Community and hospitalized care (GERI) project and the Burden of Influenza and RSV Disease (BIRD) project.
